Ugly hacks like this need at least a decent comment.
Yes, you're right but I'm always wondering if it is the good way to do
what I want: read a number of bytes instead of a number of sectors.
Perhaps I should define a new function in the qemu AIO interface ?
I think the crux of the problem is that you're using the BlockDriver API
for something that isn't actually a block driver.

There is another ugly hack, did you find it ? ;-)
